Close interval surveys (CIS) and remote monitoring units (RMUs) can be used as complimentary technologies, essential for validating safe operation of a cathodic protection (CP) system. CIS on a pipeline is typically performed once every few years due to the high cost and time commitment of the process, but the benefit is a high spatial resolution of measurements, with typical spacings between reading locations on the metre length-scale. RMUs installed at test posts with a typical spacing of multiple kilometres between units can be used to measure comparable electrical readings year-round without requiring a human to physically travel to each location.
